Backflow can pull contaminated water back into the drinking supply. We install, test and certify backflow prevention devices for strata, commercial and residential properties, and handle the Sydney Water paperwork for you.
Backflow is when a drop in pressure lets water flow the wrong way, back toward the mains. If that water has been near chemicals, irrigation, a cooling system or other contaminants, it can put the drinking supply at risk. That's why properties with higher-risk fixtures are required to have testable backflow devices fitted and tested every year.
We're accredited to install and test these devices, and we lodge the certificates with Sydney Water, so your property stays compliant without you having to chase the paperwork.
Every property is connected to the same drinking water network. A backflow device is the one-way gate that stops water from your property travelling back into that network if pressure suddenly drops, say during a mains burst or heavy demand from the fire brigade.
It's a small device doing an important job, which is why Sydney Water requires the higher-risk ones to be tested by an accredited plumber every year.
We fit the right device for the property's risk level, from simple non-testable valves up to reduced pressure zone (RPZ) devices for higher-risk sites. Then we test it, complete the certificate, and lodge it with Sydney Water.
For strata and commercial buildings with several devices, we keep track of when each one is due and remind you before it lapses, so nothing slips through.
From the first install to every annual test after.
We check the property's risk level and work out which devices are needed and where.
We fit the correct device to standard, whether that's a new install or replacing one that's failed.
We test the device, and if it doesn't pass we repair or replace it and retest so it's right.
We lodge the certificate with Sydney Water and flag the next due date so you never miss a test.
